The study aimed at examining the effects of replacing urea with protein nitrogen (N), source of protein and the quantity of rumen degradable N (RDN) in the diets of steers on rumen fermentation, outflow rate and intake. In experiment one, six ruminally cannulated Friesian steers were used in a re...

Yankasa sheep were used to study effects of palm kernel meal (PKM) on nutrient utilization and performance. The - in sacco - degradation studies revealed that potential protein degradation in the rumen was high but the very low rate of degradation (0.031 (per hour)) made 50-61 percent protein of...

The effects of 1.35, 1.8, or 2.25 kg dry matter (DM) of cottonseed cake, with (1.85 kg DM) or without molasses, on straw intake, diet digestibility, live-weight change, excretion of purine derivative (PD), and milk production of Boran (Bos indicus) cows were studied. There were no significant (P ...
